Ingredients (Serves 2–3)
For the Sushi Rice:

- 1 1/4 cups water
- 2 tablespoons rice vinegar
- 1 tablespoon sugar
- 1/2 teaspoon salt
For the Tuna Marinade:
- 8–10 ounces sushi-grade ahi tuna, diced into small cubes
- 1 tablespoon soy sauce
- 1 tablespoon ponzu or lime juice
- 1 teaspoon sesame oil
- 1 small shallot, very thinly sliced
- Optional: pinch of chili flakes or grated ginger
For the Bowl Toppings:

Instructions
Step 1: Make the Sushi Rice
- Rinse the sushi rice in a fine mesh strainer under cold water until the water runs mostly clear.
- Add the rinsed rice and 1 1/4 cups water to a pot. Bring to a boil, then reduce heat to low, cover, and simmer for 18–20 minutes. Turn off the heat and let it sit, covered, for 10 minutes.
- In a small bowl, stir together rice vinegar, sugar, and salt until dissolved. Gently fold this mixture into the warm rice with a wooden spoon or spatula. Let the rice cool to room temp while you prep the rest.
Step 2: Marinate the Tuna
- In a bowl, combine soy sauce, ponzu or lime juice, sesame oil, and optional chili flakes or ginger.
- Add in the diced tuna and shaved shallots. Toss gently to coat.
- Cover and refrigerate for 10–15 minutes while prepping toppings.
Step 3: Assemble Your Bowl
- Add a base of sushi rice to each bowl.
- Spoon the marinated tuna (with shallots) on top.
- Add sliced avocado and cucumber.
- Drizzle with Kewpie mayo and Sriracha to taste.
- Garnish with sesame seeds, green onion, or nori strips if desired.
Notes:
- Want extra texture? Add pickled ginger or crispy onions.
- Swap the tuna for salmon or tofu if needed.
- Best served immediately while the tuna is fresh and the rice is still slightly warm.
